Description

Technical Field

[0001] The utility model belongs to the technical field of blister forming molds, in particular to a blister forming structure for disposable degradable tableware. Background Art

[0002] Blister molding structure is a common plastic processing technology, usually used to manufacture various plastic products. In the field of industrial manufacturing, blister structure design is a key technology. It can be used to make various types of product shells, including disposable biodegradable tableware, electronic equipment, medical equipment, automotive parts, etc. Blister is a thermoplastic plastic processing technology. It softens the sheet by heating it, then combines the softened sheet with the mold, and uses negative pressure to adsorb the sheet to the mold surface to finally form the product shell.

[0003] The existing blister forming structure cannot ensure the integrity of the sealing inside the blister forming mold during the blister forming process. When vacuuming, the air pressure at the position of the air supply channel is relatively high, which can easily adsorb the softened plastic sheet into the hole. At the same time, the negative pressure of the vacuuming on the workpiece is uneven, which makes the thickness of the plastic workpiece uneven and the product quality cannot be guaranteed. Secondly, the existing blister forming mold requires a heating mechanism to heat the plastic sheet, which cannot make the plastic heated evenly, which is not conducive to the full fit of the plastic sheet with the mold during the subsequent blister forming process. Therefore, there is room for improvement. Utility Model Content
